Why an insulating baselayer is essential
When you head out in winter, to the mountains or in cold weather for skiing, hiking, trekking or any outdoor activity, your body is subjected to variations in temperature, humidity, exertion, stops, wind, etc. A standard or simple baselayer is often not enough to maintain lasting comfort.
An insulating base layer provides an effective thermal barrier, retains body heat, manages moisture and allows for freedom of movement. It is the first layer of your outfit: if it fails, all the layers above it will struggle to compensate.
What Therm-ic Insulating Baselayers offer
- Warmth & thermal insulation right next to the skin — Insulating baselayers are made from technical fabrics designed to retain heat close to the body and create a comfortable internal microclimate, even in very cold conditions.
-
Moisture management & prolonged comfort — By combining insulation with breathable/wicking properties, these undergarments wick away perspiration, keep the skin dry and prevent the ‘cold + damp’ effect — very important during intense exercise or in cold environments.
-
Mobility & ergonomics for outdoor activities — Designed to follow your movements, Therm-ic baselayers remain comfortable under technical clothing, without discomfort, compression or loss of freedom — ideal for skiing, hiking, expeditions or active winter living.
-
Versatility according to use & intensity — Whether for active pursuits (exercise, climbing, walking) or for periods of waiting or low movement (breaks, chair lifts, winter city life), Therm-ic insulation ensures warmth and comfort.
-
Ideal base for winter layering — As a ‘first layer,’ these baselayers prepare the body for intermediate/outer layers: insulation is provided from the outset, increasing the overall effectiveness of the equipment against the cold.
Who are these insulating baselayers for?
- Skiers, hikers, mountaineers, trekkers, winter outdoor enthusiasts — those who face cold, snow, altitude and wind.
- People who are sensitive to the cold, poor circulation or cold extremities — even without intense activity, simply staying outside for a long time justifies a good baselayer.
- Those who move around a lot (exercise, carrying, walking, climbing), or, on the contrary, alternate between exercise and immobility — because baselayers must regulate temperature and humidity according to the context.
- For all practitioners seeking comfort, warmth, freedom of movement and durability — it's a practical investment for several seasons.
Expert advice & best practices
- Wear the right baselayer for the intensity and weather — for moderate to cold exertion and temperatures: breathable insulating baselayer; for intense cold or waiting: thicker baselayer.
- Ensure a good fit—the base layer should be close to the body without being restrictive to maximise insulation and moisture wicking.
- Use in a multi-layer system—base layer + mid-layer (fleece) + outer layer (windbreaker/rain jacket) for optimal protection depending on conditions.
-
Care for it properly—gentle wash at 30°C max, no bleach, avoid fabric softener, dry flat—to preserve its thermal insulation and breathability.
- Check compatibility with the rest of your gear—trousers, jacket, insoles, socks or gloves—to ensure consistent insulation throughout your body.
